Abstract: An apparatus for drawing and ironing a cup with a peripheral flange from relatively thin material into an elongated container also having a flange by moving a die and punch relative to one another and draw clamping and centering sleeve coaxial therewith and thereafter applying a bottom forming member axially relative to the die against the punch to profile shape said container bottom without the benefit of coolant flooding of said material during drawing and ironing, the improvement comprising; a die of a predetermined shape and size carried in the apparatus, a punch of a predetermined shape and size for cooperating with said die and each having surfaces which define a clearance therebetween during forming of said material; separate passages through said die means and said punch means to permit flow of coolant; valving in line with die and punch passages for independent control of the coolant flow from a supply means to said die and punch to permit regulation of the operating temperature of said die means wit

Abstract: This disclosure relates to a product, the process for making same from precoated metal and the tool used for making the product. The product is a concurrently drawn and ironed sanitary food can wherein the side wall thickness of the container is relatively uniform and approximately 0.001" thinner than the thickness of the starting material. The process is a concurrent multiple drawing and ironing operation wherein the diameter and the wall thickness are reduced in each of a plurality of operations. Finally, the tools used for each drawing and ironing operation have particular configurations designed to permit this concurrent forming of both the diameter and the side wall thickness.
